Dear Geonwoo Lee, To avoid this error you have two possibilities:
- you can add the pencil decomposition, using -pd .true. in the mpirun line. This will make your calculations run, but probably not efficiently. - you can decrease the number of nodes and play with the combinations of nodes/k-points. Hope this helps.

One strange thing is I’m doing same job with various numbers of processors from 1 to 256 with ×2 interval. But I have been finished the job with 16 processors before but this error appears when I done with 256 processors. It seems like the message should do put something in the input file or job running command. Input and command I used are followings. Input &bands prefix='CsPbCl3', outdir='./wavefunc', filband='band', lsym=.true., / Command mpirun -f mpihost -n 256 ~/install/Quantum_Espresso_7.3.1/qe-7.3.1/bin/bands.x < bands.in > stdout.txt & tailf stdout.txt How can I avoid this error? I’m using MPI with 13 nodes with 20 cores and 32GB RAM for each nodes. I will wait for your answers.
